RIOTRONIC X+
User Manual
These conditions may include, for example:
Abrasive rocks like quartzite, granite, gneiss, basalt, etc.
The presence of water in general.
Holes deeper than 20m.
A sharp angle on the drill-holes (>15°).
Collar pipe in the holes, especially when the collar pipe is removed before firing.
Drill-holes which include large holes, pockets of earth and any other irregularities
likely to make loading difficult and cause stress on the wires.
Decked charges.
These conditions may lead to:
Damage to the RIOTRONIC X+ detonator wires.
Damage to the bus-line.
Damage to the RIOTRONIC X+ detonators due to high dynamic pressure.
Potential results could be:
Lack of communication or communication errors between the RIOTRONIC X+
detonators and the RIOTRONIC X+ Logger or Blaster.
Electric current leakage.
Partial misfires.
5.8. Limiting the risk of wire damage
To limit the risk of damaging the RIOTRONIC X+ detonator wires during the preparation
and installation of the priming cartridge:
Place the RIOTRONIC X+ detonator in the lower third of the priming cartridge,
making sure that the wire does not pull excessively on the crimping assembly of the
RIOTRONIC X+ detonator.
Miners’ knots increase the diameter of the cartridge and lead to weak points being
exposed to abrasion along the inner walls of the drill holes. The knots limit the
amount of play needed to allow the cartridge to slide down the hole easily.
Use electrical tape to ensure that the RIOTRONIC X+ detonator wire is properly
connected to the cartridge and that the wire is protected for the entire length of the
priming cartridge.
Lower the cartridge down carefully, by slowly un-spooling the RIOTRONIC X+
detonator wire and avoiding free fall.
